The invention relates to a nickel-boron-antimony-co-doped stannic oxide electrical catalytic anode which is prepared by impregnating the surface of a porous titanium plate with an anode coating and calcining the same. The anode coating is prepared from the following components in parts by mole: 600-700 parts of citric acid, 100-200 parts of ethanediol, 100-150 parts of stannic chloride, 5-10 partsof antimony trichloride, 0.5-2 parts of nickel dichloride and 2-4 parts of boric acid. The anode provided by the invention aims to solve the problem that in the prior art, an electrical catalytic anode is high in price and short in service life. The nickel-boron-antimony-co-doped stannic oxide electrical catalytic anode is prepared by means of a method of impregnating a gel coat and calcining ata high temperature, and has the technical advantages of high catalytic activity and stability, low production cost and good phenol degrading effect.
